Standard Specification for

Hard-Drawn Copper Alloy Wires for Electric Conductors

1

This standard is issued under the fixed designation B 105; the number immediately following the designation indicates the year of

original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A

superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This specification covers hard-drawn round copper alloy

1.3 The SI values of density and resistivity are to be

regarded as standard. For all other properties the inch-pound

2.2 ASTM Standards:

B 193 Test Method for Resistivity of Electrical Conductor

B 258 Specification for Standard Nominal Diameters and

E 527 Practice for Numbering Metals and Alloys (UNS)

2.3 Other Document:

NBS Handbook 100—Copper Wire Tables

3. Ordering Information

3.1 Orders for material under this specification should

14.1),

3.1.6 Special package marking, if required, and

3.1.7 Place of inspection (see

13.1).

4. Material and Manufacture

4.1 The material used shall be copper alloys of such nature

and composition as to secure by proper treatment the properties

prescribed in this specification for the finished wire.

5. Chemical Composition

5.1 The chemical composition of copper alloy wires shall

ments to be found in any one of the alloys is prescribed in

Table 2. If the purchaser elects to check the composition of any

material supplied to conform to the performance requirements

of any one of the alloys, the composition limits should be made

the subject of a definite agreement between the manufacturer

and the purchaser in the placing of individual orders.

6. Chemical Analysis

6.1 An analysis may be made on each lot of 5000 lb (2300

kg) or fraction thereof. Millings or clippings shall be made

from at least ten separate coils. Equal quantities shall be taken

This specification is under the jurisdiction of the ASTM Committee B01 on

Electrical Conductors and is the direct responsibility of Subcommittee B01.04 on

Conductors of Copper and Copper Alloys.
